LIGHTWEIGHT COMPOSITE OVERWRAPPED PRESSURE VESSELS WITH SECTIONED LINERS
First Claim
1. A lightweight composite overwrapped pressure vessel comprising:
- (i) a liner housing body comprising a plurality of sections assembled together to form said liner housing body, wherein a peripheral edge of a first section comprises a channel such that a peripheral edge of a second section that is juxtaposed with said first section forms a slot; and
(ii) a composite overwrap material encasing said liner housing body and providing mechanical strength for holding said liner housing body under pressure and providing a sealing means to prevent leakage of a fluid medium contained within said liner housing body.

Abstract
The present invention provides a lightweight high pressure vessels that are made from a liner or a liner housing that is overwrapped with a composite material. Unlike conventional high pressure vessels, the lightweight high pressure vessel of the invention includes a liner that comprises a plurality of liner sections without using welding or crimping. In particular, the lightweight high pressure vessels of the invention include a plurality of elements that are combined to form a liner housing and a composite overwrap that provides structural and mechanical strength to maintain integrity of the high pressure vessel. In one particular embodiment, the high pressure vessel of the invention is a diaphragm accumulator.

7. A lightweight composite overwrapped diaphragm accumulator comprising:
-
(i) an accumulator housing comprising; (a) top and bottom liner sections joined together to form said accumulator housing, wherein a peripheral edge of one of said top or bottom liner sections contains a channel such that the peripheral edges of top and bottom liner sections that are joined together forms a slot, and wherein said top and bottom liner sections comprise first and second orifices, respectively, for introducing first and second pressure mediums, respectively; and (b) a diaphragm subdividing an interior of said accumulator housing into first and second pressure medium storage areas, said first pressure medium storage area accommodating first pressure medium, said second pressure medium storage area accommodating second pressure medium, wherein a peripheral edge of said diaphragm is inserted into said slot, thereby securing the peripheral edge of said diaphragm therebetween; and (ii) composite overwrap encasing said accumulator housing and providing mechanical strength for holding said accumulator housing under pressure and to provide a sufficient stiffness and mechanical strength to prevent leakage of first or second pressure medium. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16, 17)
